C API crashes when invalid mesh is used by a BVH or can't be cleaned up

cadop opened this issue · comments

Currently just experienced with Unity when creating a BVH with 0 vertices, the C API will crash when trying to use this invalid mesh for raycasting.

While this isn't a priority since it only happens when incorrectly setting the BVH, it would be nice to have a more graceful exit.

Crash also happens if a BVH or Graph is setup and isn't cleaned up.
